Genes affected

SMURF2 (HGNC:16809): (SMAD specific E3 ubiquitin protein ligase 2) Enables SMAD binding activity; identical protein binding activity; and ubiquitin-protein transferase activity. Involved in negative regulation of transforming growth factor beta receptor signaling pathway; positive regulation of trophoblast cell migration; and ubiquitin-dependent SMAD protein catabolic process. Located in nuclear speck. Part of ubiquitin ligase complex. [provided by Alliance of Genome Resources, Apr 2022]

The c.874A>G (p.N292D) alteration is located in exon 10 (coding exon 10) of the SMURF2 gene. This alteration results from a A to G substitution at nucleotide position 874, causing the asparagine (N) at amino acid position 292 to be replaced by an aspartic acid (D). Based on insufficient or conflicting evidence, the clinical significance of this alteration remains unclear. -
